Explanation:
Using the ratio and Isla's counters' number, find the total number of counters.
Let the multiplier be x, then the ratio is 6x : 5x : 7x, where Isla's number is 6x, which is 12.
Total number of counters is:
Find the multiplier using initial ratios:
- 36 ÷ (5 + 4 + 3) =
- 36 ÷ 12 =
- 3
Find the initial number of counters Isla had:
